It happens in X session, both on my development machine, updated from Fedora 23 and a new clean machine install from Fedora alpha iso without any modifications.
This an incarnation of https://bugzilla.mozilla.org/show_bug.cgi?id=1245783 - we have to disable JS JIT engine because of the gcc6 miscompilation. So js code is extremely slow here.
Jakub, is it possible to backport https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70526 to Fedora gcc package? Thanks.
Do you mean to GCC 6 or GCC 5? For GCC 6, gcc-6.0.0-0.20.fc{24,25} should have it already, except that it is still building (for almost 2 days!!!) on the slooooooooooooooooooooow armv7hl. This arch should never been primary!
Thanks, I may try it build locally then. I mean gcc6, Fedora 24 and rawhide. If the bug also affects gcc5 it may not be a cause of the JIT crashes...but let's see.
This message is a reminder that Fedora 24 is nearing its end of life. Approximately 2 (two) weeks from now Fedora will stop maintaining and issuing updates for Fedora 24. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '24'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 24 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
